RepForge

Workout logger with AI coaching, analytics & Health Connect integration
RepForge is a privacy-first workout logging app that helps you track sets, reps, and weights across customisable routines.

All workout data is stored locally on-device using Hive. No account required. No data is sent to any server unless you explicitly configure the optional AI Coach feature with your own API key.

FEATURES

• Log workout sessions with sets, reps, and weights
• Visualise progress with charts (volume, strength curves)
• AI-powered set recommendations using on-device linear regression
• Customisable exercise library with 50+ built-in exercises
• Goal tracking with ML-estimated completion dates
• Reusable workout routines
• Health Connect integration for sleep and heart-rate readiness scores
• Optional AI Coach powered by Google Gemini (requires a user-supplied API key)
• Full data export/import for portability

PRIVACY

RepForge is fully offline by default. The optional AI Coach feature sends data to Google's Gemini API only if you provide your own API key in Settings → AI Settings. The app works completely without it.
